Field of the Invention The present invention relates to a pressure-sensitive adhesive sheet and a sheet-like light emitting structure, and more particularly to a pressure-sensitive adhesive sheet and a sheet-like light emitting structure having a luminous property and shining in a dark place.

Description of the Related Art As shown in FIG. 9, most conventional pressure-sensitive adhesive sheets having a light-storing property have a light-storing layer 31 that is not transparent and a pressure-sensitive adhesive layer 32 on the back surface thereof. A structure having a printing portion 33 printed directly on the surface 31 is used. FIG. 9 illustrates a case where the pressure-sensitive adhesive layer 32 of such a conventional pressure-sensitive adhesive sheet is pressed against the surface 34 to be bonded of another object to be bonded.

施す等の手段を要した。In FIG. 9, an arrow L
1 and L 2 indicate light emission from the light storage layer 31 toward the outer surface. Since the printed portion 33 made of printing ink covers the outer surface of the phosphorescent layer 31, the light emission L 1 can be seen from the portion where the printed portion 33 does not exist, but the light emission occurs at the portion where the printed portion 33 exists. Since L 2 was shielded, the essential print was dark (not shining), and it was inconvenient for decoration and various displays and markers. In addition, since the phosphorescent layer 31 is located on the outer surface,
Since 31 is liable to be contaminated and scratched, and the deterioration of the phosphorescent pigment is apt to proceed at an early stage, a means such as transparent clear printing is required on the upper portion.

Further, a light-transmissive light-storing layer was laminated on the high light-transmissive film, and a transparent adhesive layer was laminated on the light-storing layer. In addition, a high light-transmissive film, a light-transmissive light storage layer, a transparent adhesive layer, and a separator are sequentially laminated.

A configuration in which the adhesive layer 3 is simply laminated, that is, a configuration in which the separator 4 in FIG. 1 is omitted may be adopted. Alternatively, as shown in FIG. 3, the transparent adhesive layer 3 may be laminated on the back surface of the translucent light-storing layer 2.

ある。The highly transparent film 1 as the base film is preferably made of PET, PP, PVC or the like, which is as colorless and transparent as possible and has a high transparent property, and its light transmittance T 1 is 80% to 99.9. Set to%. The reason is T
When 1 is less than 80%, the amount of light that reaches the phosphorescent layer decreases, and the time required to store the light increases. Further, the film transmittance of light emitted from the luminous layer is low, which is a problem.

Disperse the thickness H of the phosphorescent layer 2 2 10 μm to 60 μm
And The reason is that the phosphorescent face that can be dispersed below 10 μm
The fee is low and the luminous effect is low. Transparent when 60 μm or more
The amount of resin used increases, resulting in higher costs. Also, predetermined
It is difficult to secure the light transmittance of.

It is better to set it to 0). If the amount of the phosphorescent pigment is less than the lower limit value, the sufficient phosphorescent function is not exhibited. On the other hand, when the amount of the light-emitting pigment exceeds the upper limit, the cost becomes high, it becomes difficult to obtain sufficient transmittance, and the strength becomes brittle. As the transparent resin, acryl-based, PE-based, urethane-based or the like can be used.
